Answer:

x=27

Step-by-step explanation:

We have been given a diagram of 2 triangles and we are asked to find the value of x.

We can see that triangle CDQ and RDB share a common angle and line CQ is parallel to line RB.

Since the corresponding angles formed by two parallel lines are equal, therefore,

m\angle DQC=m\angle DBR

m\angle DCQ=m\angle DRB

As all the angles is both triangles are equal, therefore, \Delta CDQ\sim\Delta RDB.

As both triangles are similar, so their corresponding sides will be proportional.

We can set a proportion for the sides of our given triangles as:

\frac{x}{18}=\frac{39}{26}

\frac{x}{18}*18=\frac{39}{26}*18

x=\frac{3}{2}*18

x=3*9

x=27

Therefore, the value of x is 27.
